Figure 2-1
Mark Tube for Nozzle Spacing
2. Using mounting clamps (1), mount nozzles (2) on
boom at marked locations. Refer to
2-4 and Figure 2-5 for correct placement of end nozzles and tee-nozzles. When mounting nozzles on the
left-hand, inside boom arm, mount nozzles on the in
side of the arm. Mount all other nozzles to the rear.
Figure 2-3, Figure
17077
3. Plumb nozzles. From the roll of 3/4-inch hose , cut
lengths to connect the nozzles. Use worm clamps to
secure hoses to nozzles. Refer to
2-4 and Figure 2-5 for correct placement of tee-fittings
(1) and feed lines. Use zip ties (2) and hose holders
(3) to secure the hoses.
4. Route boom hoses through center of A frame on
boom and on the front left of boom carrier. Make a
loop in the hose so that when the elevator is fully
raised, there is enough slack in the hose.
5. Tie hoses to the horizontal and left vertical tube of
boom carrier. Zip ties hoses tight so they can not slide
in and out of the tie. When routing the hoses from the
elevator to the ball v alves, be sure there will be no
kinking, drooping, or rubbing when sprayer is in oper
ation. Use cable ties where needed to secure the hose
on sprayer.
6. Attach boom hoses to the three boom valves. Make
sure left boom feed-line hose is connected to the front
valve (front being tow ard the hitch). The left hose and
valve are marked with a red tape . Attach center boom
feed-line hose to the middle valv e which is mark ed
with yellow tape. The right boom feed-line hose should
be connected to the rear valve which is marked with
green tape.
7. Fold and unfold the boom wings to check an y pinch
points where the hose may become damaged. Unfold
-
the boom, remove the boom le v el-float loc k pin and
rock the boom to check any pinch points around the
swing-arms. Use zip ties to fasten hoses to pre v ent
hose damage.
8. Check to see all nuts are tightened. See the Torque
V alues Chart,
that all hose clamps are tight.
9. Fill sprayer tank 1/4 full of w ater. Hook up the pump to
a tractor and operate the pump with control box boom
switches off and agitation wide open. If unit is
equipped with boom throttling valves, open throttling
valves full open. With pump running turn on all boom
switches and flush out boom lines before assembling
nozzles. Allow water to flow out of all nozzles at least
ten seconds to ensure all foreign material is removed
from the plumbing.
